[lockdep] Runtime lock dependency tracking library.

This is a set of template types that implements runtime lock
dependency tracking to detect lock ordering problems based on
online observations of locking patterns. The approach uses only
statically allocated data structures and lock-free, wait-free
algorithms to track and analyze the runtime program behavior.

Bug: ZX-23
Test: k ut lock_dep_tests passes.
